Tonight a slew of improv pros will attempt to scratch your comedy itch in the most hysterical way possible during the "Bar Brawl" fundraiser at the Allentown Brew Works in Allentown.

All of the proceeds from tonight's show will benefit "Growth," a program of Philadelphia-based Resources for Human Development. The program provides life-sharing and unlicensed home and community habilitation for those with intellectual developmental disabilities and autism.

Admission costs $5. Doors open at 7:30 p.m. Show time is 8 o'clock.

The evening's featured performers are: 2Plus1 Math Rocks!, Aunt 'Merica, Cat Sweaters, Cranks & Pulleys, The Fourtets, Just Us, Little Torpedo and Not Making Friends Theatre.

Fair warning: "Improv Bar Brawl" is intended for mature audiences.

The Allentown Brew Works is located at 812 W. Hamilton St.
